Although the delta and RASTA methods have been widely used in extracting the temporal properties of stationary features for robust speech recognition, there is still a need to investigate new temporal features for better performance. In this paper, we present two new temporal features for robust processing of speech signals with emphasis on microphone variations. First, the temporal feature is ...

BACKGROUND Patient movement has been considered an important source of errors in cardiac PET. This study was aimed at evaluating the effects of such movement on myocardial blood flow (MBF) and perfusable tissue fraction (PTF) measurements in intravenous ¹⁵O-water PET. METHODS Nineteen ¹⁵O-water scans were performed on ten healthy volunteers and three patients with severe cardiac dysfunction u...

Plasmid pTC-F14 is a 14.2-kb plasmid isolated from Acidithiobacillus caldus that has a replicon that is closely related to the promiscuous, broad-host-range IncQ family of plasmids. The region containing the mobilization genes was sequenced and encoded five Mob proteins that were related to those of the DNA processing (Dtr or Tra1) region of IncP plasmids rather than to the three-Mob-protein sy...

Nkx3.1 is a homeoprotein transcription factor (TF) that inhibits proliferation of prostate epithelial cells (PECs) and acts as a tumor suppressor for prostate cancer (PCa). Because TFs classically function within the cells that produce them, Nkx3.1-induced growth inhibition was considered to occur in a cell-autonomous manner. We, however, found that Nkx3.1 protein can be secreted from cultured ...

PTF (PSE-binding transcription factor) activates transcription of snRNA and related genes. We investigated its distribution in HeLa nuclei by immunofluorescence, and found it spread throughout the nucleoplasm in small foci. In some cells, PTF is also concentrated in one, or very few, discrete regions (diameter approximately 1.3 micron) that appear during G1 phase and disappear in S phase. Oct1,...

Optimization of a Wireless Sensor Network (WSN) downlink with an energy harvesting transmitter (base station) is considered. The base station (BS), which is attached to the central controller of the network, sends control information to the gateways of individual WSNs in the downlink. This paper specifically addresses the case where the BS is supplied with solar energy. Leveraging the daily per...

UNLABELLED Combined Pituitary Hormone Deficiency (CPHD) is a prevalent disease in Neuroendocrinology services. The genetic form of CPHD may originate from mutations in pituitary transcription factor (PTF) genes and the pituitary image in these cases may give a clue of what PTF is most probably mutated: defects in LHX4 are usually associated with ectopic posterior pituitary (EPP); defects in LHX...

OBJECTIVES To create awareness to the radiologist and clinicians for the magnetic resonance imaging (MRI) appearance of Pterygopalatine fossa (PTF) tumours and to evaluate the role of MRI in the diagnostic of PTF lesions. METHODOLOGY Retrospective evaluation of MRI features of 29 patients with pathologically proved pterygopalatine fossa (PTF) lesions was performed. The study included 18 males...

A micro-perforated panel (MPP) with a backing cavity is a well known device for efficient noise absorption. This configuration has been thoroughly studied in the experimental conditions of an acoustic tube (Kundt tube), in which the MPP is excited by a normal incident plane wave in one dimension. In a more practical situation, the efficiency of MPP may be influenced by the vibro-acoustic behavi...
